VETERINARY SURGICAL TABLE,

Application filed August 17,1928. Serial No. 300,206.

This invention relates to new and useful improvements in veterinary surgical tables, and of the character shown in my prior pending application, Serial No. 172,728, filed March 4, 1927. Y

An object of the present invent-ion is to provide a surgical table comprising a bottom having spaced side members adapted for lateral. adjustment to vary the space between them, and the means for laterally adjusting said members, comprising a pair of ratchet bars fixed to one of the side members and adapted to be engagedby suitable pawls to lock the side members in adjusted positions.

A further object of the invention is to provide a veterinary surgical table comprising a bottom having spaced side members or walls, one of which is fiiied to the bottom and the other one being laterally adjustable with respect to the fixed member, to vary the space between them, and a pair of ratchet bars being secured to the movable side member and slidable in recesses provided in the bottom, the opposite ends of said ratchet bars extending from one side of the table and having hand grips for the convenience of the operator in "adjusting the position oi? the movable side member, and a pair of pawls being mounted upon the stationary side member or wall and normally yieldably engaging the ratchet bars to lock them in adjusted positions, and an operating lever being mounted between the pawls and connected therewith, whereby the two pawls may be simultaneously moved out of engagement with their respective ratchetvbars to permit the movable side member to be moved outwardly in a direction away from the stationary side member.

A further object is to provide a veterinary surgical table of the class described, comprising a bottom having spaced side walls, each having a beveled or wedge-shaped member secured to the inner sides thereof adjacent to one end of the table and against which the animals head is placed, when positioned on the table, and a block being adjustably mounted on each side wall adjacent to said wedge-shaped members adapted to engage the neck of the animal between the head and shoulders to more securely hold the animal therein, 7

provided in the stationary side member or wall of the table, and'having its other leg slidably mounted in a guide provided on the edge of thetable bottom, said guide having a recessed portion to permit its complementary legfto be moved out of engagement therewith when. the head rest is moved to the limit of its upward movement, thereby permitting the head rest to be, swung'to an 'out-of-Ithewvay position at one side of the table, and the head rest also-being adapted for vertical adjustment. v

A further object is to provide a veterinary surgical table having a leg-locking device mounted at the foot end of the table, comprising a substantially U-shaped member having one end or leg connected to an arm pivotally and slidably mounted on means provided upon the stationary side member or wall of the table Which permits the leglock ing device tobe adjusted vertically with respect to the tablebottom, and which means also permit the leg lock to be adjusted longitudinally with respect to the table so as to position it to properly engage the animal to secure it to the table.'

A further object is to provide a veterinary sm'gical table pivotally mounted upon a suitable standard and adapted for tilting movement, and having a notched bar pivotally connected with one side thereof adapted to engage a pin provided upon the standard, to support the table in an operative position.

The particular object of the invention, therefore, is to provide an improved veterinary surgical table having means for adapting it to animals of di'llerent sizes, and

furtheiy having means for securing the ani-v mal therein. I 4

Other objects of the invention will appear from the following description andwill be pointed out inthe annexed claims.

In the accompanying drawings forming Figure 3 is a detail sectional view on the line 33 of Figure 2;

Figure 4 is a'detail sectional view on the The means provided,for laterally adjusting t-he'side wall 4 consists of a pair of ratchetbars 6, each having one end bent upwardly and secured to the side member by suitable bolts'T, shown in Figure 3. The bars 6 are slidable in recesses 8 providedin the top'surface of the bottom 2, and pass beneaththestationary Wall 3 and extend outwardly therefrom, and. each has a handle portion 9 terminally provided thereon for the convenience of the operator in-moving the side member inwardly towards the stationary wall member 3. In the drawings, I have shown the bottom 2 composedof a plurality ofsections or strips suitably secured togetherby means of tie bolts 11, as shown in Figure 2. The strips are arranged to provide open spaces or gaps 12 in the intermediate portion of the bottom 2.

Ratchet teeth 13 are provided on the inner ed es of each bar-'6 adapted to be engaged by a pairof latch members or pawls let, pivotally mounted upon the stationary wall member 3, as shown in Figure 1. An operat ing lever 15 is. pivotally mounted on the fixed wall member 3 between the pawls 1 1,

- and has rods 16 connecting it with the pawls.

A tension spring 17 has one end connected to the upper end of the lever 15 and its opposite end to a clip 18 secured to the fixed wall' member 3. This spring constantly tends'to urge .the pawls 14 into engagement with the ratchet teeth 13, as shown in Figure 1. A handle 19 is provided at one end of the lever 15, whereby the latter may be conveniently. oscillated to move the .pawls out of locking engagement with the ratchet teeth 13. The connections bet-ween the pawls and the lever 15 are so arranged that when the handle 19 of the lever is moved to the left, as shown in Figure 1 the two pawls will simultaneously be movedout of locking engagement with the ratchet teeth against the tension of the spring 17. When the handle 19 is released, the spring will move the pawls into locking engagement withthe ratchet teeth, as shown in Figure 1.

A head locking device is provided at the head end of the table andcomprises a U- shaped member 21 having legs 22 and 23,

the latter being slidably mounted in an aperture or guide provided in the stationary wall member 3, as best shown in Figure d. A washer 24 and pin 25 are provided at the lower end of the leg, 23 to limit upward movement of the locking device. A set screw26 isreceived in threaded engagement with a plate 27 and provides means for locking the head lock in adjusted positions. The leg 22 is slidablyreceived in a guide or clip 28, secured to the opposite edge of the bottom 2. This leg is also slightly shorter than the leg 23 so that When the locking member is in the full line position, shown in Figure l,

the leg 22 may be swung out of engagement with the clip or guide 28, as indicated in dotted lines in Figure 5.

To permit'the leg 22 to be moved out of engagement with the clip 28, as above described, the latter is provided with a recessed or cut-away portion 29, as shown in Figure 5, which permits the lower end of the leg to be moved out of engagement therewith when the leg is in its uppermost position, as shown in full lines in Figure 4.

By thus mounting the head lock 21 upon the table, it may be ve:tically adjusted with V respect to the bottom 2 and the wall member 4 may also belaterally adjusted without interference therewith, as the wall member is not directly engaged therewith. The leg 22 also provides a, stop for limiting outward movement of the wall member l, as shownin Figure l A small clip 31. is provided at the opposite end of the table bottom 2 and co-operates with the leg 22 tolimit the outward movement of the wall member l.

The opposite end of the table is provided with a leg locking device for securing the rear port-ion of the animals body in position upon the table. This leg. locking device comprises ei-shaped member 32, preferably tubular in cross section, and having one end secured to a slotted arm 33 slidably and pivotally mounted upon a bolt 34, securely mounted in a bracket secured to the stationary wall member 3 by suitable 36, (see Figures 1 and An arcuately formed slot 37 is provided in the bracket 35 and hasa bolt 38 movably mounted therein, which also passes through a slot 39 provided in the arm 33. A crank 11 is received in threaded engagement with the bolt 38 and provides means for locking the arm 33 to the bracket 35 to secure the leg rest- 32 in adjusted positions. The head of the bolt 38 is so engaged with the bracket to prevent relative rotation thereof when the crank 41 is rotated.

By thus mounting the leg rest 32 upon the stationary wall member 3 of the table, it will readily be seen that the leg lock may be vertically adjusted with respect to the table, and also by means of the slots 37 and 39, the locking member 32- may be longitudinally adjusted with respect to the table. The opposite end of the locking member 32 is not engaged with the table top or with the movable wall member 4, thus permitting said wall member to be laterally adjusted without interfering with the locking memher.

A wedge-shaped member 42 is preferably secured to the head end of each'wall memher, as shown in Figures 1 and 2, to shape the inner forward end portions of the wall -1nembers to more closely conform to the shape of the animals head. A vertically disposed block 43 is adjustably secured to each wall member adjacent the wedgeshaped members 42. These blocks are adjustable longitudinally with respect to the table, and are held in adjusted positionsby means of wing nuts 44 and bolts 45, the latter passing through slots 46, provided in the side walls 3 and 4, as indicated in dotted lines in Figure 2 and also shown in Figure 5. The blocks 43 are adapted to engage the neck of the animal between the head and shoulders to more firmly secure the animal in position upon the table.

The supporting means for the table comprises a suitable standard including 47, preferably having their lower ends socured to members 48, and having their upper ends engaged with studs 49, preferably terminally provided upon a bar 51, secured to the bottom of the table by suitable bolts 52 (see Figures 1 and 2). The inclined members 4'? of the standard are connected together by suitable cross members 50, shown in Figure 1. Nuts secure the upper ends of the legs to the studs 49.

A bar 54 is pivoted at 55 to one edge of the bottom 2, and has notches 56 therein adapted to selectively engage a pin 57 se cured to one of the legs 47. When the bar 54 is engaged with the pin 5'7, as shown in Figure 1, the table will be supported in substantially a horizontal position. The notches 56 in the bar 54 permit the table to be adjusted to various angular positions with respect to the legs 47 The novel veterinary surgical table shown and described in this invention may be used for holding various sizes of animals, for such purposes as vaccinating, drenching, ringing, ear-marking, worming, and other surgical operations. The head and leg locking members are so arranged that they may be quickly moved out of the way of the top of the table to permit the animal to be placed thereon, after which they may be quickly moved into locking engagement with the animals, body to firmly hold the animal on the table. The means provided for adjusting the locking and movable side member 4 in its adjusted positions, permits the latter to be moved into engagement with the body of the animal, after the latter has been placed upon the table; the pawls 14 automatically movingi'into locking engagement with the ratchet teeth 13, as the bars 6 are moved in the direction indicated by the arrow in FigureB. Because of the head and leg locking members 21 and 32, respectively, not engaging the movable wallmemher 4, the latter may be adjusted without op erating these locking members, as will readily be seen by reference to Figures 1 and 3.

The notchedbar ,54 also provides .means for quickly tilting thetable to any desired position. The leg-locking member 82 is so arranged that it may be used for holding the animals legs either in an extended position or folded forwardly against its body.- When the operation has been'completed, the animal may be quickly released from the table by simply releasing the leg-locking member 32 by rotation of the crank'41;'rel.easing the head rest by rotation of the wing nut 28, and by releasing the grip on the animals body by operating the lever handle 19 to permit the movable side member 4 to be moved out of engagement with the body of the hog, after which the bar 54 may be moved Jout of engagement with the pin 57, and the table tilted to a positionto permit the animal to be slid from the table.
